Question

In the following question, the symbols $@,\copyright ,\%,\$$ and $\star$ are used with the following meaning as illustrated.
${}^{\prime }P\copyright Q^{\prime }$ means 'P is not greater than Q'.
${}^{\prime }P\star Q^{\prime }$ means 'P is not smaller than Q'.
${}^{\prime }P\%Q^{\prime }$ means 'P is neither greater than nor equal to Q'.
${}^{\prime }P\$Q^{\prime }$ means 'P is neither smaller than nor greater than Q'.
${}^{\prime }P@Q^{\prime }$ means 'P is neither greater than nor smaller to Q'.
In each of the following questions assuming the given statements to be true, find out which of the three conclusions I, II and III given is/are definitely true.
© $\Rightarrow \le$, @ $\Rightarrow$ = $\star \Rightarrow \ge$, % $\Rightarrow$ < $\$$ $\Rightarrow$ >
Statements
$J\$D$
$D\copyright K$
$K\%R$
Conclusions
I. $R\$J$
II. $R\$D$
III. $K\$J$

• A. None of these
• B. Only I is true
• C. Only II is true
• D. Only III is true
• E. Only II and III are true

Answer 1

The correct option is C Only II is true

Given statements are
J $\$$ D $\Rightarrow$ J > D ...(i)
D © K $\Rightarrow D\le K$ ...(ii)
K % R $\Rightarrow K\le R$ ...(iii)
After combining these statements, we get J > D $\le$ K < R
I. R $\$$ J $\Rightarrow$ R > J = False, as relation cannot be established here.
II. R $\$$ D $\Rightarrow$ R > D = True
As, D $\le$ K < R
So, R > D is true
III. K $\$$ J $\Rightarrow$ K > J = False
As, J > D $\le$ K
So, relation cannot be established.
